Composite construction combines two very different materials in a manner that maximizes the benefits of each. In the Alpha Comp Hoody we use Fortius 1.0 stretch woven fabric to regulate heat and provide stretch through core and under the arms. N40p 3L laminated GORE® Product Technology provides durable weather protection across the hood, shoulders, forearms and hem.
